Purpose The mechanism of IOP change during a body position change is poorly understood. In this study, we investigated changes in episcleral venous pressure (EVP) between two body positions, sitting and inclined, and compared this with changes in IOP. Methods This study was a prospective, comparative case series of 43 eyes of 24 healthy volunteers. IOP was measured using a pneumatonometer in ...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

The aim of this study was to identify possible anatomical risk factors for Kienbock's disease. We measured on a posteroanterior radiograph of the wrist, in zero-position, the Lunate Diameter and Height, Lunate Tilting Angle, Lunate Uncovering Index, Lunate Fossa Inclination, Radial Inclination and Ulnar Variance. We measured these seven parameters on the unaffected hand in the Kienböck group (N...

The concept of a 'deformable arm scale' (completely different from a traditional rigid arm balance) is theoretically introduced and experimentally validated. The idea is not intuitive, but is the result of nonlinear equilibrium kinematics of rods inducing configurational forces, so that deflection of the arms becomes necessary for equilibrium, which would be impossible for a rigid system. In pa...

We present large-scale parallel direct numerical simulations of granular flow using a novel, portable software program for Discrete Element Method (DEM) simulations. Since particle methods provide a unifying framework for both discrete and continuous systems, we base the program on the ppm library [1], which has already been demonstrated to provide transparent parallelization and state-of-thear...

The prolonged low-level static load on the back during sitting can be hypothesized to an effect back muscles adversely. Westgaard and DeLuca [1] indicated that prolonged low-level activity of muscle influenced on higher muscle activity of other muscle group. Fifty four years ago Keegan [2] established the relation between trunkthigh angle and lumbar spine curvature. Keegan found that angle of 1...

Authentication is the process to provide guaranteed information security and the graphical password authentication method is a convenient and easy process to provide authentication. The major problem of user registration, mostly text base password, is well known. If the login user be inclined to select a simple password which is frequently in his mind it becomes straightforward for attackers to...

The major problem of user registration, mostly text base password, is well known. In the login user be inclined to select simple passwords which is frequently in mind that are straightforward for attackers to guess, difficult machine created password mostly complicated to user take in mind. User authenticate password using cued click points and Persuasive Cued Click Points graphical password sc...

Declarative approaches to process modeling are regarded well suited for highly volatile environments as they provide a high degree of flexibility. However, problems in understanding and maintaining declarative process models impede their usage. To compensate for these shortcomings, Test Driven Modeling (TDM) has been proposed. This paper reports on an empirical investigation in which TDM is vie...

To investigate hydrodynamic performance of the end cover under different inclined angles, a series of 3-Dimensional geometric models of the end cover with different inclined angles were built by Creo. The maximum inclined angle is 32 degrees and the minimum is 6 degrees. Numerical simulations by solving the Navier-Stokes equation, coupled with the “k-ɛ” turbulence model, were carried out. At la...
